Definitions

  • the present invention is related to an apparatus and method for orienting a tubular heat-shrinkable sleeve relative to a container.
  • Heat-shrinkable sleeves are known in the art. These sleeves can be used to add decoration or other information to a container. For instance, a sleeve may comprise a printed image to display a brand name or information regarding the contents of the container. Such sleeves are commonly used in the food and beverages industry, beauty products industry, etc.
  • the sleeves are typically arranged around the containers using a high throughput process in which the containers are guided using conveyor belts. Separate sleeving stations may be arranged to arrange a sleeve around the container. This is normally done from either the top side or bottom side relative to the conveyor belt.
  • the application of sleeves is known in the art and a more detailed explanation is therefore deemed unnecessary.
  • the container and sleeve are transported through a shrinking device, such as a heating tunnel, wherein under the application of heat, the heat-shrinkable sleeve shrinks thereby fixedly attaching itself to the container.
  • a shrinking device such as a heating tunnel
  • angular orientation will be defined relative to an axis perpendicular to the conveyor belt that is used to transport the containers or relative to a longitudinal axis of the container.
  • Solutions are known for mutually orienting the sleeve and container.
  • the container is moved, more in particularly rotated, to position the container such that the sleeve, which is assumed to have a well-defined orientation, can be placed accurately on the container.
  • the containers are gripped at the top side, for instance at the lid or cap of the container.
  • Separate container belts may be used that touch the lid or cap of the container to be rotated.
  • the conveyor belts are arranged along the transport direction of the main conveyor belt that supports the containers.
  • a separate conveyor belt is arranged on either side of the main conveyor belt, wherein the two conveyor belts may move in opposite directions and at a different speed as the main conveyor belt. Consequently, as the container is conveyed by the main conveyor belt it is rotated by the two oppositely arranged conveyor belts.
  • a first drawback is the throughput that can be achieved with this solution.
  • the container which is typically filled, is relatively heavy, it takes some time before the container is rotated.
  • the forces exerted by the conveyor belts, which are arranged on either side of the main conveyor belt, onto the container cannot be too excessive as this may cause the container to tumble.
  • the rotation takes time, and, because the container is moving, the apparatus responsible for the rotation must extend along a considerable length.
  • a further drawback related to the rotation of the containers by gripping the lid or cap is related to the amount of force that must be exerted by a consumer for opening the lid or cap. It has been shown that the forces exerted onto the cap or lid for the purpose of rotating the container may result in the cap or lid being fastened too tightly. The opposite may also occur, wherein the cap or lid is loosened during the process of rotating the container.
  • An even further drawback is related to the achievable mutual orientation of the sleeve and container. More in particular, a current trend in the industry is to apply various processing techniques after the sleeve has been shrunk onto the container. An example of such processing technique is embossing or cutting parts of the sleeve away using a laser to make room for the handle of the container. In particular when the container is highly asymmetric, the achievable orientation of sleeve and container using the known solution is not satisfactory.
  • Still another drawback is also related to the use of asymmetric containers.
  • the container has a particular shape, for instance a cartoon character shape
  • the sleeve comprises a printed image that should correspond to this shape
  • the sleeve must be arranged even more accurately on the container.
  • the container comprises protrusions on a lateral side of the container that correspond to the nose of a cartoon character.
  • the printed image could correspond to an image of a nose, eyes etc. It should be obvious that this image must be aligned perfectly in order to achieve an appealing look of the final product. Even if the container can be orientated perfectly with respect to the sleeve, it cannot be guaranteed that the printed image on the sleeve is positioned sufficiently accurate. This is related to the fact that the process of printing an image on the sleeve is also subjected to tolerances. The known solution does not account for these tolerances.
  • EP 1457427B1 discloses an apparatus, in accordance with the preamble of claim 1, controlling the relative position of a bottle and a sleeve.
  • a video system may be used to monitor the orientation of the sleeve relative to the bottle.
  • a feedback loop and reorienting mechanism are used to correct misalignment between the bottle and the sleeve.
  • the reorienting mechanism may be a mechanical belt such as a belt system for adjusting the sleeve position.
  • the applicant has found that the known apparatus is not able to provide a constant quality of the sleeve when it is shrunk around the container.
  • this object has been achieved with an apparatus according to claim 1, which is configured for orienting a tubular heat-shrinkable sleeve relative to a container around which the heat-shrinkable sleeve has been arranged, wherein the sleeve has not yet been finally shrunk.
  • the sleeve is being transported along a transport direction, preferably either in a continuous or an intermittent manner.
  • the apparatus comprises a conveyor having a moveable conveyor belt for transporting the container in the transport direction, and a determining unit for determining an angular position difference between the container and the sleeve, preferably relative to an axis perpendicular to the conveyor belt.
  • a conveyor belt comprises a flat surface on which the container is supported.
  • the angular orientation may be defined relative to an axis perpendicular to this flat surface.
  • the angular orientation may also be defined relative to another axis, preferably relative to the longitudinal axis of the sleeve.
  • the heat shrinkable sleeve Prior to orienting the sleeve relative to the container, the heat shrinkable sleeve has not yet been finally shrunk. In some applications, the sleeve may nevertheless be loosely attached to the container not excluding the case in which a small part of the sleeve has been shrunk to keep the sleeve in place during transport. In this situation, the process of orienting the sleeve relative to the container in accordance with the present invention breaks the connection between sleeve and container. Then, after the sleeve is properly orientated relative to the container, it may be finally shrunk in for instance a heat tunnel.
  • the apparatus according to the invention further comprises a sleeve orientation unit that comprises a support surface, preferably arranged downstream of the determining unit and preferably at least on one side of the conveyor belt, wherein the support surface is arranged at a distance from the container(s) that is or are transported preferably on the conveyor belt, and wherein the support surface is moveable in a direction parallel to the transport direction.
  • the sleeve orientation unit could further comprise a support surface drive unit for moving the support surface at a predefined speed.
  • the sleeve orientation unit comprises a holding unit configured to hold the sleeve against the support surface
  • the sleeve orientation unit could comprise a control unit configured to determine a speed at which the support surface moves and/or a holding time during which the sleeve is held against the support surface based on the determined angular position difference and to control the holding unit and/or support surface drive unit using the determined holding time and/or speed.
  • the sleeve orientation unit is configured is rotate the sleeve relative to the container in dependence of an angular position difference between the container and the sleeve by moving the support surface while the sleeve is held against the support surface.
  • the sleeve will be held against the support surface, whereas the container will generally not touch the support surface. Furthermore, the sleeve may move at a different speed along the transport direction than the container. Due to this difference in speed, the container may at some point in time hit the sleeve either at the front or back side of the container. If the sleeve is released at or just prior to that point in time, the sleeve will return to a position around the container in which the angular position relative to the container has been changed. This is particularly the case when the sleeve is held against a support surface on only one side of the conveyor belt.
  • the amount of change in angular position can be determined by varying the holding time during which the sleeve is held against the support surface and/or the speed of the support surface. It is also possible to not move the support surface at all, in which case the holding time is relatively short due to the large difference in speed between the support surface and the conveyor belt.
  • the present invention allows orienting the sleeve without exerting a force onto the sleeve that is directed towards the container. If such force is exerted, the sleeve may wrinkle or otherwise deform in a more or less unpredictable manner. When the force is removed, for instance at the end of the orienting, the sleeve will regain its natural form. The motion of the sleeve from the wrinkled or deformed state to its natural form will in general be accompanied by an unpredictable change in angular position of the sleeve relative to the container.
  • the sleeve orientation unit could be configured to rotate the sleeve while the sleeve is moving in the direction parallel to the transport direction.
  • a pair of the sleeve orientation units may be employed, wherein the sleeve orientation units are arranged on opposite sides of the conveyor belt.
  • the control units of the sleeve orientation units may cooperate or may be integrated into the same unit.
  • the control unit may be configured to control the support surface drive unit to rotate the sleeve from a starting position to an end position, wherein the sleeve is rotated from the starting position directly to the end position, or the sleeve is first rotated from its starting position to a predetermined reference position, and then rotated from the reference position to the end position, or the sleeve is first rotated in a first direction over a first angle, and then rotated over a second angle in a second direction opposite to the first direction.
  • the support surface may first move in a first direction, and then move in a second direction opposite to the first direction.
  • a difference in speed at which and/or a time during which the support surface moves between the movements along the first and second directions may depend on the determined angular position difference.
  • the sleeve may for instance turn 175 degrees clockwise followed by a rotation of 180 degrees counterclockwise.
  • a net rotation of 5 degrees counterclockwise is achieved. Obtaining a 5 degrees rotation in this manner may be more reproducible than a single rotation of 5 degrees counterclockwise. This approach is particularly suitable if a pair of oppositely arranged sleeve orientation units is used.
  • the support surfaces of the oppositely arranged sleeve orientation units may each move at a speed that comprises a common part and a differential part, wherein the common parts are equal in both direction and magnitude, and wherein the differential parts are equal in magnitude but have an opposite direction.
  • Vcontainer and Vsleeve represent the common and differential part, respectively.
  • This configuration of speeds allows the sleeve to be rotated while it is moving at the same speed as the container.
  • the invention is not limited to this configuration.
  • the common part may be zero or at least different from the speed of the container.
  • the apparatus may further comprise a further determining unit configured for determining a further angular position difference between the container and the sleeve downstream of the sleeve orientation unit.
  • a further determining unit configured for determining a further angular position difference between the container and the sleeve downstream of the sleeve orientation unit.
  • At least one of a return unit and a rejection unit may be arranged downstream of the sleeve orientation unit, wherein the return unit is configured to return a container and sleeve to a position on the conveyor belt upstream of the sleeve orientation unit and determining unit if the further angular position difference exceeds a first predefined threshold, and wherein the rejection unit is configured to remove a container and sleeve from the conveyor belt if the further angular position difference exceeds a second predefined threshold.
  • the control unit may further be configured to determine a correlation between the angular position difference and control parameters for the support surface drive unit needed for correcting the difference, wherein the control unit is configured to determine the correlation using a self-learning algorithm that compares the angular position difference, the control parameters used for correcting this difference, and the further angular position difference observed after correcting the difference.
  • Example control parameters may be the speed of the support surface(s), the holding time for each support surface, a time used for acceleration between different speeds of the support surface(s), etc.
  • the determining unit may comprise a first detector for detecting the angular position of the sleeve, preferably relative to the axis perpendicular to the conveyor belt, wherein the first detector preferably comprises an optical camera.
  • the optical camera may be configured to detect folding lines or seams in the sleeve, a printed image on the sleeve, or other physical structures to determine the angular position.
  • the sleeve may comprise an identifiable first reference point, such as an area or feature in a printed image on the sleeve.
  • the first detector may be configured to detect the angular position of the sleeve by identifying the first reference point, preferably relative to the axis perpendicular to the conveyor belt.
  • the angular position of the sleeve can be determined by comparing the identified first reference point to a corresponding first reference point in a first reference image, wherein the angular position associated with the first reference image and/or the first reference point in that first reference image is known.
  • an optical camera may be used to record an image of the sleeve that is arranged around the container. The recorded image may be compared with a first reference image.
  • the reference image may correspond to the image that has been printed on the sleeve. It may further correspond to a particular angular position of the sleeve.
  • the sleeve position refers to the position of the printed image on the sleeve instead of the position of the physical sleeve itself.
  • the reference image corresponds to a particular position of the printed image on the sleeve that is known.
  • a deviation between images can be determined, for instance a shift or rotation, and from this deviation the angular position of the sleeve, e.g. the angular position of the printed image on the sleeve, may be determined.
  • image matching techniques can be used.
  • features or particular areas in the images can be identified.
  • the position of a specific feature in the reference image for instance the center region of a specific color patch, may be compared to the position of this same feature in the recorded image.
  • the container may comprise an identifiable second reference point, such as a physical structure, for example a recess or a protrusion, wherein the first detector is configured to determine the angular position difference from a distance between the first and second identifiable reference points.
  • the angular position difference can be determined from a single recorded image of both the sleeve and container.
  • the angular position of the container has a known value or has been set to a known value upstream of the determining unit and sleeve orientation unit, wherein the angular position difference is determined by the determining unit or the control unit by comparing the detected angular position of the sleeve with the known value. In this case, there is no need to determine the angular position of the container as this value is known.
  • the sleeve may comprise a folding line. Furthermore, the sleeve may have been arranged around the container, upstream of the sleeve orientation unit, in a manner that the orientation of the folding line relative to the container is known. For instance, a guiding unit may be arranged upstream of the sleeve orientation unit that engages the folding line and guides the sleeve to a position around the container, wherein the container itself has a know position. Alternatively, this position is detected using a detector similar to the first detector or the second detector that will be described later on. Such detector may be coupled to a container orientation unit that corrects the angular position of the container based on the detected angular position of the container.
  • the angular position difference between the physical sleeve and the container may be known upstream of the sleeve orientation unit.
  • this does not mean that the angular position of the sleeve of interest, meaning the angular position of an image printed on the sleeve is known.
  • the angular position of the sleeve relative to the folding line may have shifted.
  • This angular offset between the image printed on the sleeve relative to an intended position of the image on the sleeve can be detected upstream of the apparatus according to the invention.
  • this angular offset may be detected by the first detector, wherein the determining unit is configured to determine the angular position difference between the sleeve and container by comparing the angular offset and the known orientation of the folding line relative to the container.
  • the determining unit may comprise a second detector for detecting the angular position of the container, preferably relative to the axis perpendicular to the conveyor belt, wherein the second detector preferably comprises an optical camera.
  • the container may comprise an identifiable second reference point, such as a physical structure, for example a recess or a protrusion, and wherein the second detector is configured to detect the angular position of the container by identifying the second reference point, preferably relative to the axis perpendicular to the conveyor belt.
  • the angular position of the container can be determined by comparing the identified second reference point to a corresponding second reference point in a second reference image, wherein the angular position associated with the second reference image and/or the second reference point in that second reference image is known.
  • the first and second detectors may be combined, although the invention is not limited thereto.
  • the determining unit may be configured to determine the angular position difference by subtracting the angular positions of the sleeve and the container as determined by the first and second detectors, respectively.
  • the first and second detectors may be identical. For instance, a single optical camera may be used to perform as the first and second detector, possibly simultaneously. In this last case, a single recorded image is used to determine the angular position difference.
  • the first and/or second detector may configure to detect the angular position of the sleeve and/or container from the side, the top and/or the bottom.
  • Various techniques can be employed to determine the angular position. For instance, scanning techniques, such as laser scanning may be used to detect the angular position by identifying protrusions, recesses, seams, folding lines, etc.

  • a gaseous medium such as pressurized gas
  • Such gaseous medium may assist in freeing the sleeve from the wall(s) of the container.
  • the support surface could be movable relative to the one or more openings and the sleeve orientation unit could be configured to rotate the sleeve by moving the support surface relative to the one or more openings.
  • the vacuum unit could comprise a vacuum chamber connectable to a vacuum pump, wherein the vacuum chamber has an open end, and wherein the support surface is preferably arranged in or near the vacuum chamber in a manner partially covering the open end.

  • the one or more openings comprise the perforations in the conveyor belt.
  • the vacuum chamber may comprise a plurality of segments along the transport direction, wherein the vacuum is separately adjustable and/or different in each segment. As an example, a vacuum level of the most downstream segments is reduced with respect to other segments. This enables sleeves to gradually detach from the support surface to allow a smooth transition between the state in which the sleeves are held against the support surface and the state in which they are freely arranged around the container. It may even be possible to define vacuum profiles, indicating the level of vacuum along the support surface in the transport direction. For instance, when the support surface is formed by a conveyor belt that extends between a pair of wheels/rollers, the vacuum may be defined to be less near the wheels/rollers, to ensure a properly defined vacuum in between the wheels/rollers.

  • FIG. 2E illustrates the velocity vectors 40, 50, 60, corresponding to left support surface 4, container 20, and right support surface 4, respectively.
  • Velocity vector 40 comprises a common part, which equals velocity vector 50 of container 20, and a differential part 45.
  • velocity vector 60 comprises a common part, which equals velocity vector 50 of container 20, and a differential part 55.
  • differential parts 45, 55 are equal in magnitude but are opposite in direction.
  • sleeve 30 will rotate counterclockwise while at the same time advancing at the same speed as container 20. It should be noted that the common part may be set to zero. This may for instance apply when conveyor belt 1 stops during the sleeve orientation, or when the displacement of container 20 during the sleeve orientating is negligible.
  • sleeve 30 can be released from support surface 4 as shown in figure 2D . This can be achieved by switching off the vacuum, by gradually reducing the vacuum, or simply because support surface 4 ends as shown in figure 1 .
  • control unit 9 will control support surface drive units 6 using a plurality of control parameters.
  • the support surfaces are configured to move at a well defined speed during the sleeve orientation.
  • the only relevant parameters may be the speed of the support surface and/or the holding time during which the sleeve is held against this support surface.
  • the speed is not constant as the support surface may accelerate or decelerate between speeds.
  • the acceleration or deceleration constant, or the time during which the support surface changes speeds as well as the starting and ending speed may form control parameters.
  • Control unit 9 may be self-learning. For instance, it may use input from optical cameras 15 which record a further angular position difference downstream of sleeve orientation units 3. The determination of the further angular position difference may be performed similar to the determination of the angular position difference upstream of sleeve orientation units 3. Control unit 3 may determine a correlation, such as a lookup table, between the upstream angular position difference, the control parameters that are used to correct this difference, and the resulting downstream angular position difference. The correlation should enable control unit 9 to select the appropriate control parameters to reduce the angular position difference to acceptable levels.

  • the vacuum unit arranged inside sleeve orientation unit 3, attracts sleeves towards supporting conveyor belts 4.

  • Figure 4B illustrates an example of a comparison between a reference image of a sleeve and an image recorded by an optical camera 10 of sleeve 30.
  • sleeve 30 is at the same position as the sleeve in the reference image, and that sleeve 30 is only rotated compared to the sleeve in the reference image.
  • a difference 82 in position can be observed between the position of feature 31a in recorded image 80 and the corresponding position of the same feature 31b in reference image 81.
  • reference image 81 corresponds to the situation wherein the printed image is arranged in the middle. This is not mandatory.
  • the observed difference can be used to compute the angular position difference.
  • Figure 5 illustrates an example of a method in accordance with the present invention.

  • step S1A an image is recorded of the container itself.
  • step S2 a feature in the recorded image of the sleeve is detected.
  • This feature is also present in a reference image of the sleeve, wherein the reference image is associated with the sleeve in a predefined or otherwise known angular position.
  • step S2A a feature is also detected in the recorded image of the container.
  • This feature is also present in a reference image of the container, wherein the reference image is associated with the container in a predefined or otherwise known angular position.

  • step S5 the angular position difference between the sleeve and container is determined. This difference is determined using the determined angular position of the sleeve, and optionally the determined angular position of the container. Based on the angular position difference, a holding time and/or speed of the support surface(s) of the sleeve orientation unit can be determined in step S6.
  • step S7 gas is optionally blown into the sleeve in step S7 to enable the sleeve to detach from the container.
  • step S8 gas is optionally blown into the sleeve in step S7 to enable the sleeve to detach from the container.
  • step S8 the sleeve is held against the support surface in step S8 based on the determined holding time and/or speed.
  • step S9 the sleeve is rotated with respect to the container, preferably by moving the support surface(s) at the determined speed with the sleeve held there against and/or by holding the sleeve during the determined holding time.

  • the reference image of the sleeve may correspond to a sleeve rotation of 10 degrees.
  • an offset may be determined. Assuming that the sleeve is not rotated, an offset of -10 degrees may be calculated.
  • a change in speed of the support surfaces is calculated based on the determined offsets.
  • step S104 the calculated value in step S103 is inverted. Consequently, the changes in speed for the support surfaces on opposite sides of the conveyor belt are opposite in sign.
  • the support surfaces on both sides of the conveyor belt move at a speed that equals the speed of the conveyor belt on which the container is transported. This speed is the common speed, denoted as Vcontainer.

  • the invention allows the mutual orientation of the sleeve and container.
  • the physical structure of the sleeve and/or a printed image thereon can be oriented with respect to a physical structure of the container.
  • a printed image on the container may equally be used.
  • the angular position difference could also directly be determined, for instance using a single recorded image, in which image the necessary features of the sleeve and container can be identified.
  • the position of the camera can be varied depending on the feature to be captured. For instance, some protrusions can best be captured by a camera mounted above the container, whereas a printed image on a sleeve can best be determined by mounting a camera in a horizontal manner facing the sleeve.
  • the present invention does not exclude the possibility of simultaneously orienting a plurality of sleeves relative to a plurality of containers.
  • This may be advantageous if the angular position difference between sleeve and container is relatively large for each of the plurality of sleeve container combinations.

  • each sleeve container combination can be individually mutually oriented to correct for differences in the angular position difference between different sleeve container combinations.
  • control parameters used for orienting the sleeve may be adapted based on an angular position difference between sleeve and container determined downstream of the sleeve orientation unit.
